I'm really confused by the columns system in Bootstrap. Here is what I have:
<div class="container-fluid">
<!-- Page Heading -->
<div class="d-sm-flex align-items-center justify-content-between mb-4">
  <h1 class="h3 mb-0 text-gray-800">Cards</h1>
</div>
<div class="row">
  <!-- Earnings (Monthly) Card Example -->
  <div class="col-xl-2 col-md-2 mb-2">
    <div class="card border-left-primary shadow h-100 py-2">
      <div class="card-body">
        <div class="row no-gutters align-items-center">
          <div class="col mr-2">
            <div class="text-xs font-weight-bold text-primary text-uppercase mb-1">Stop</div>
            <div class="h5 mb-0 font-weight-bold text-gray-800">8</div>
          </div>
          <div class="col-auto">
            <span class="material-icons">
              pan_tool
              </span>
             
          </div>
        </div>
      </div>
    </div>
  </div>
I have 8 cards total and 2 of them fall in the second line, because of spacing. How can I achieve a professional view with my cards? I need to show 12 different status of machines we have, start, stop, and run.
